MACHINE FOR MOLDING BASES ON FENCE-POSTS.

To (LZZ who n'it may concern).- Be it known that I, CHARLES S. LONG,citizen of the United States, residing in Au rora, in the county of Kaneand State of Illinois, have invented a new and useful Im. I provement 1nMachines for Molding Bases on Fence Posts, of which the following is aspecification.

' This invention relates to the construction of machines for moldingbases of cement or other material onto metallic fence-posts.

My endeavor in the invention has been to devise a construction of suchmachines adapted to be operated by manual power and which is so simpleas to require no skilled labor inits operation and which is so cheap tomanufacture as to bring it within the means of the average farmer, sothat the farmer, who is the principal user of such posts, will beenabled to provide the metal posts with bases at his home.

The invention consists in the novel construction of parts and devicesand novel combinations of parts and devices hereinafter set forth.

In the accompanying drawings I show at Figure 1 an end elevation of myinvention, at Fig. 2 a section on the line A A of Fig. 1, and at Fig. 3a section on the line B B of Fig. 2.

My invention employs a horizontal mold of the proper size and shape forthe base of the post, and this mold is divided horizontally along itscentral plane. The lower half 6 of the mold is formed in the base 7 andthe upper half 8 in a movable block 9. The ends of the mold are formedpartly by the vertical portions 10, which are attached to or in onepiece with the lower half of the mold, and by the vertical pieces 1 1,inclosing the open ends of the upper half of the mold. The pieces 11 areconnected together by longitudinal pieces 12, and the pieces 11 and 12together form a complete frame, which is adapted to rest upon the top ofthe lower half-mold, being coincident with the latter in shape anddimensions and also adapted to serve as a guide to the block 9 in itsmovements. At each side of the mold are two uprights 13, arrangedopposite each other in pairs and each provided with an overhanging hook14, the interior of which serves as a bearing for the journals 15 of theeccentric-shafts 16. These shafts extend transversely across the aparatus and are located over the ends of the Specification of LettersPatent. Application filed September 6, 1904. Serial No. 223,327-

block 9, and each shaft is provided with an eccentric 17 and with anoperating handlever 18.

Arranged longitudinally of the top surface of the block 9 is a slot 19,in which I place loose rollers 20. These rollers receive the pressurefrom the eccentrics and communicate the pressure to the block 9, wherebythe latter is forced down and creates the pressure upon the plasticmaterial forming the base of the fence-post, and in order to creategreater or less pressure it is only necessary to substitute otherrollers 20 for those shown, largersized rollers increasing the pressureand smaller ones diminishing it, as will be readily understood. Therollers are seated in the ends of the slot when the eccentrics begin tobear upon them, and they are free to turn with the eccentrics.

The metal portion 21 of the fence-post is positioned in the mold byforming an opening 1n the ends 10 and 11 corresponding to the shape ofthe post. Thus in the instance shown the post is made of What is knownas Y metal, and the ends 10 and 11 are fashioned to fit such shape. Ifit is desired to use different-shaped metal, of course thesupportmg-opening in the end of the mold will be changedcorrespondingly.

In the use of the apparatus the metal post is positioned as shown and ameasured quantity of the cement or other lastic material of which thebase is to be formed is positioned in the lower half of the mold, theframe 1 1 12 being preferably in position upon the lower half-mold. Theblock 9 is then inserted in the frame, and the shafts are placed in thehooks of the uprights, with the levers thrown back from the positionsshown at Fig. 2. The rollers 20 being placed in the slot of the block 9in readiness to engage the eccentrics, the levers are then forced overto the position shown at Fig. 2. In this operation the eccentrics bearupon the rollers 20 and carrv' the block 9 down to the necessary extentto create the reqluired compression upon the plastic materia in themold. After the compression has been retained for the necessary lengthof time for the setting of the material the levers are reversed from theposition of Fig. 2 and the eccentric shafts removed. This leaves theframe 11 12 and the block 9 at liberty to be lifted off, so that thepost, with its molded base, may be then removed.

I posts, having a lower stationary half-mold with closed ends, an uppermovable halfmold with open ends, a frame closing the ends of the upperhalf-mold, and also serving to guide the upper mold, and means forforcing the upper mold down on the plastic material an opening beingformed in the end of the lower mold and the frame at the meeting line ofthe same for the insertion and support of the fence-post.

2. The machine for molding bases on fenceposts, having a lowerstationary half-mold with closed ends, an upper movable halfmold withopen ends, a frame surrounding the upper mold and resting on the lowerone, and serving both to close the ends of, and to guide the upper mold,and means for forcing the upper mold down on the plastic material.

8. The machine for molding bases on fenceposts, having a lowerstationary half-mold, an upper movable half-mold, a guide-frame fittedto and resting on the top of the lower mold and serving to guide theupper mold,

and means for forcing the upper mold down upon the material.

4. The machine for molding bases on fenceposts, consisting of a lowerstationary halfmold, an upper movable half-mold, a guideframe,manually-operated eccentrics for forc ing the upper mold down upon thelower one, and rollers in said upper mold engaged by the eccentrics.

5. The machine for molding bases on fenceposts, consisting of a lowerstationary halfmold, an upper movable half-mold, a guideframe,manually-operated shafts carrying eccentrics for forcing the upper molddown upon the lower one, and loose rollers in said upper mold engaged bythe eccentrics.

6. The machine for molding bases on fenceposts, consisting of a lowerstationary halfmold, an upper movable half-mold, a guideframe,manually-operated shafts carrying eccentrics for forcing the upper molddown upon the lower one, and loose rollers located in a slot formed inthe top of the upper mold and engaged by the eccentrics.

7 The machine for molding bases on fenceposts, consisting of a lowerstationary halfmold, an upper movable half-mold, a guideframe, hookeduprights mounted on the lower mold, shafts supported in said uprightsand carrying eccentrics, changeable rollers supported in the upper moldand engaged by v the eccentrics.
